2006-09-08[PATCH] IA64,sparc: local DoS with corrupted ELFsKirill Korotaev1-12/+15
This prevents cross-region mappings on IA64 and SPARC which could lead to system crash. They were correctly trapped for normal mmap() calls, but not for the kernel internal calls generated by executable loading. This code just moves the architecture-specific cross-region checks into an arch-specific "arch_mmap_check()" macro, and defines that for the architectures that needed it (ia64, sparc and sparc64). Architectures that don't have any special requirements can just ignore the new cross-region check, since the mmap() code will just notice on its own when the macro isn't defined.

2006-07-13[SPARC]: Fix OF register translations under sub-PCI busses.David S. Miller1-58/+109
There is an implicit assumption in the code that ranges will translate to something that can fit in 2 32-bit cells, or a 64-bit value. For certain kinds of things below PCI this isn't necessarily true. Here is what the relevant OF device hierarchy looks like for one of the serial controllers on an Ultra5: Node 0xf005f1e0 ranges: 00000000.00000000.00000000.000001fe.01000000.00000000.01000000 01000000.00000000.00000000.000001fe.02000000.00000000.01000000 02000000.00000000.00000000.000001ff.00000000.00000001.00000000 03000000.00000000.00000000.000001ff.00000000.00000001.00000000 device_type: 'pci' model: 'SUNW,sabre' Node 0xf005f9d4 device_type: 'pci' model: 'SUNW,simba' Node 0xf0060d24 ranges: 00000010.00000000 82010810.00000000.f0000000 01000000 00000014.00000000 82010814.00000000.f1000000 00800000 name: 'ebus' Node 0xf0062dac reg: 00000014.003083f8.00000008 --> 0x1ff.f13083f8 device_type: 'serial' name: 'su' So the correct translation here is: 1) Match "su" register to second ranges entry of 'ebus', which translates into a PCI triplet "82010814.00000000.f1000000" of size 00800000, which gives us "82010814.00000000.f13083f8". 2) Pass-through "SUNW,simba" since it lacks ranges property 3) Match "82010814.00000000.f13083f8" to third ranges property of PCI controller node 'SUNW,sabre', and we arrive at the final physical MMIO address of "0x1fff13083f8". Due to the 2-cell assumption, we couldn't translate to a PCI 3-cell value, and we couldn't perform a pass-thru on it either. It was easiest to just stop splitting the ranges application operation between two methods, ->map and ->translate, and just let ->map do all the work. That way it would work purely on 32-bit cell arrays instead of having to "return" some value like a u64. It's still not %100 correct because the out-of-range check is still done using the 64 least significant bits of the range and address. But it does work for all the cases I've thrown at it so far.

screen_info.h doesn't have anything to do with the tty layer and shouldn't be included by tty.h. This patches removes the include and modifies all users to directly include screen_info.h. struct screen_info is mainly used to communicate with the console drivers in drivers/video/console. Note that this patch touches every arch and I have no way of testing it. If there is a mistake the worst thing that will happen is a compile error.

2006-06-30[PATCH] zoned vm counters: conversion of nr_pagecache to per zone counterChristoph Lameter1-1/+1
Currently a single atomic variable is used to establish the size of the page cache in the whole machine. The zoned VM counters have the same method of implementation as the nr_pagecache code but also allow the determination of the pagecache size per zone. Remove the special implementation for nr_pagecache and make it a zoned counter named NR_FILE_PAGES. Updates of the page cache counters are always performed with interrupts off. We can therefore use the __ variant here.

2006-06-29[SPARC]: sparc32 side of of_device layer IRQ resolution.David S. Miller1-7/+62
Happily, life is much simpler on 32-bit sparc systems. The "intr" property, preferred over the "interrupts" property is used-as. Some minor translations of this value happen on sun4d systems. The stage is now set to rewrite the sparc serial driver probing to use the of_driver framework, and then to convert all SBUS, EBUS, and ISA drivers in-kind so that we can nuke all those special bus frameworks.

2006-06-20[SPARC]: Kill __irq_itoa().David S. Miller5-32/+0
This ugly hack was long overdue to die. It was a way to print out Sparc interrupts in a more freindly format, since IRQ numbers were arbitrary opaque 32-bit integers which vectored into PIL levels. These 32-bit integers were not necessarily in the 0-->NR_IRQS range, but the PILs they vectored to were. The idea now is that we will increase NR_IRQS a little bit and use a virtual<-->real IRQ number mapping scheme similar to PowerPC. That makes this IRQ printing hack irrelevant, and furthermore only a handful of drivers actually used __irq_itoa() making it even less useful. Signed-off-by: David S. Miller <davem@davemloft.net>
